In one embodiment of the present invention, a coaxial cable connector is provided. A coaxial cable connector, as shown in
Please refer to
The inner sleeve of the coaxial cable connector has a perforation 102 along the axial direction of the coaxial cable connector, a first outer flange 104, a second outer flange 106, a first surface 108 and a first rear extension 110, wherein the cross sectional of the perforation 102 has an annular shape, and the perforation 102 is disposed between the first outer flange 104 and the second outer flange 106, wherein the rubber ring 16 surrounds the annular shape of the perforation 102, and the second outer flange 106 is located between the first surface 108 and the first outer flange 104, with the first surface 108 located between the first rear extension 110 and the second outer flange 106.
The nut 14 of the coaxial cable connector has a perforation 142 along the axial direction of the coaxial cable connector, a first inner flange 144 and an inner threaded surface 146, wherein the nut 14 can be in a hexagonal nut, square, annular nut, wing or any other suitable shape such that it can be locked to an electronic device by using a wrench or other tools. The diameter of the perforation 142 of the nut 14 is respectively greater than that of the second outer flange 106 and the first rear extension 110 of the inner sleeve 10 but less than the diameter of the first outer flange 104. The first rear extension 110 of the inner sleeve 10 can pass through the perforation 142 of the nut 14 so as to dispose the first inner flange 144 of the nut 14 on the second outer flange 106. Furthermore, the nut 14 can rotate on the second outer flange 106, wherein when the first inner flange 144 of the nut 14 is moved toward the first outer flange 104, the first inner flange 144 of the nut 14 can press the rubber ring 16 in the groove 112 to deform the rubber ring 16 with a side surface of the first outer flange 104 abutting against the first inner flange 144 of the nut 14, so that the deformed rubber ring 16 can fill the gaps between the first inner flange 144, the second outer flange 106 and the first outer flange 104 of the nut 14 for achieving the waterproof effect.
The outer sleeve 12 of the coaxial cable connector has a perforation 122 along the axial direction of the coaxial cable connector, a second inner flange 124, a third outer flange 126, a second rear extension, a second surface 130 and a third surface 132. The third outer flange 126 surrounds the outer surface of the outer sleeve 12 between the second surface 130 and the second rear extension 128, wherein the diameter of the perforation 122 is greater than that of the first rear extension 110 of the inner sleeve 10 but less than that of the second outer flange 106. Additionally, the third surface 132 is an outer surface of the second inner flange 124, and the maximum diameter of the top surface of the third outer flange 126 is greater than the diameter of the third surface 132. The first rear extension 110 of the inner sleeve 10 can pass through the perforation 122 of the outer sleeve 12 so as to dispose the second inner flange 124 of the outer sleeve 12 on the first surface 108. The second inner flange 124 is engaged with the first surface 108 in a tightly-fitting manner. At this time, the second rear extension 128 and the first rear extension 110 form an annular space therebetween, wherein the third outer flange 126 (including the front and rear ends of the third outer flange 126) is located outside the annular space. Additionally, a front end of the third outer flange 126 is located radially outside the annular space. The axial distance between the front end of the third outer flange 126 and the rear end of the outer sleeve 12 is greater than twice of that between the front end of the third outer flange 126 and the front end of the annular space; or the axial distance from the third outer flange 126 to the rear end of the outer sleeve 12 is greater than 1.5 times of that between the rear end of the third outer flange 126 and the front end of the annular space. Also, the first inner flange 144 of the nut 14 is axially movable between the second inner flange 124 of the outer sleeve 12 and the first outer flange 104 of the inner sleeve 10 and is freely rotatable on the second outer flange 106 when assembly is completed.
As shown in
As shown in
The plunger 202 is pushed so that the recess 208 of the plunger 202 can accommodate the metal wire 1 located in the inner threaded surface 146 and abut against the nut 14 and the first outer flange 104 of the inner sleeve 10. The plunger 202 then pushes the coaxial cable connector 100 to the cone-like perforation 210 formed by the combined first and second molds 204 and 206, at this time, the second rear extension 128 of the outer sleeve 12 will abut against the inner wall of the cone-like perforation 210, wherein during a period a push force is applied to the coaxial cable connector 100 by a user, the second rear extension 128 of the outer sleeve 12 is radially pressed and deformed into a cone-like shape; that is, the diameter d1 of the second rear extension 128 adjacent to the outer sleeve 12 is reduced to a diameter d2, wherein the diameter d1 of the second surface 130 remains unchanged and the gap between the second rear extension 128 and the first rear extension 110 becomes smaller so as to press the metal braided layer 7 and the plastic jacket layer 9, so that the coaxial cable and the coaxial cable connector 100 can be tightly engaged with each other to avoid peeling off. Then, when the third outer flange 126 of the outer sleeve 12 abuts against the first stepping part 204a and the second stepping part 206a, the coaxial cable connector 100 will no longer move, indicating deformation of the second rear extension 128 of the outer sleeve 12 has been carried out. The first mold 204 and the second mold 206 are then separated from each other to remove the coaxial cable connector 100 with the coaxial cable.
As shown in
The third outer flange 126 on the outer sleeve 12 provides a timely blockage when the mold is deformed by pressing so that the coaxial cable connector 100 is easily removed from the mold assembly and the outer sleeve 12. The third outer flange 126 allows the user to grip it easily, making it easier to mount the coaxial cable to the coaxial cable connector 100.
Though the embodiment of the present invention have been shown and described, it will be understood by those skilled in the art that such embodiments can be varied without departing from the principles and spirit of the present invention.
Unless otherwise stated, all measurements, values, ratings, positions, magnitudes, sizes, and other specifications that are set forth in this specification, including in the claims that follow, are approximate, not exact.
